The designations employed and the presentation of material on the maps do not imply the expression of any opinion whatsoever on the part of the European Union concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries. [...] At this equilibrium point, the yield and the percentage of juvenile fish in the catch are quantified for each of the selectivity patterns and compared to the equilibrium values attained from projections based on the current selectivity for Fcur and, in addition, based on the scientific advice for F (ICES / GFCM). [...] An adjustable decribing the descending where denotes a normal probability density distribution, S_{max} corresponds to the mean of the normal distribution where peaks, determines the slope of the descending limb with the standard deviation of the normal given by the product , and determines the mimimum the descending slope (height). [...] To address ToRs 1, 2 and 20 20 3 (b) the percentage of juveniles in the catches is computed as ratio of the number immature to the total number of fish in the catch in addition to (a) the relative change yield (%). [...] RESULTS FOR ALL STOCKS In analogy to the results elaborated on above, Tables 4.1.2.1 and 4.1.2.3 display, for each stock, the percentage gain in yield, compared to the current selectivity, of the four scenarios as well as the current percentage of juveniles in the catch and under the same four scenarios; all at the end of the projected time series in the year 2070 (when equilibrium has been reache.
